Vulnerability Overview

WordPress Core failed to sufficiently sanitize block attributes in versions up to, and including, 6.2. This makes it possible for authenticated attackers with contributor-level and above permissions to embed arbitrary content in HTML comments on the page, though Cross-Site Scripting may be possible when combined with an additional vulnerability.
